i have an idea about creating a second world in a dream. and then in a next dream, convincing my subconscious, to go back into the same dream. does anybody have any ideas to accomplish this???(or has)if anyone would like to write there ideas or progress here please do so!

I often revisit beaches and tropical islands in my lucid dreams, and sometimes I feel I'm on a beach I've been to before. Usually though because it's a representation of a beach in real life!

I feel that there might be an issue trying to return to the exact same "world" in a lucid dream - because it implies that the world exists permanently, even when you aren't there. Which is a nice thought but probably unlikely.

I believe there are no constants in lucid dreams (except maybe our own awareness, but even that has a tendency to shift!) and so returning to the same place would only be an illusion at best, and would very likely keep changing as is typical of dreams.

Here would be one way to probe this theory. Go to your childhood house in a lucid dream, and place an object there, preferably from the present day or something that doesn't belong.

Then go back to the same house on a separate night and see if your special object is still there. If it is, it would suggest some kind of continuity of the dreamworld (or of your subconscious). But most likely the object will be gone, and the house may even look different too.

This doesn't stop you from returning to your favorite places of course. I am just curious as to whether an independent part of the dream world could exist without our participation.
